Checking the Dice
Roll two dice, multiple times into a level area, by hand and using the shaker; note the results. Fair dice will score 7 the most times, followed by 6 and 8; 5 and 9; 4 and 10; and 3 and 11, with 2 and 12 rolled the least. Allow for slight variations.
Feel the weight distribution. Loaded dice would feel unevenly balanced. Loaded dice can be made to favor any number, though 6 and 1 are the most common examples.
Check that all numbers occur. Add up the opposite sides of the dice -- all should equal 7.
Shake, Rattle and Roll
Use a shaker, as required in backgammon, whenever possible. This eliminates the possibility of controlling the roll of the dice when thrown by hand, as in craps.
Be aware of the lock grip. When this is employed the dice thrower will shake his hand, and you will hear the dice rattle, but the dice will not have moved out of position.
Be aware of dice setting. Combined with the lock grip, this method of holding the dice eliminates two sides of each die landing uppermost, thus reducing the odds. The thrower will hold two die faces against each other as they are thrown.
Be aware of the controlled roll. This occurs when the dice rotate about just one axis, again reducing the odds of how they come to rest.
Check the condition of the area that the dice land on. A surface sprinkled with salt causes the dice to slide rather than roll. Altering the angle of trajectory can influence the outcome of the throw.
The Rules
Implement the "cocked dice" rule. If any die is not flat on its base, all dice must be rolled again.
Implement the "bounce-back" rule. All dice must bounce off a wall, as in craps.
Implement the "dice on table" rule. If any dice rolls out of bounds, all dice must be re-rolled.
